Review Comment:
if the `initialSavepointPath` is not present the job will be restarted from
empty state. At least that's how I implemented and documented it. We could
discuss whether this should be allowed or not. The stateless upgradeMode serves
this purpose to some extent but then the user has to change the upgradeMode
back and forth
